Micro-chipping BP

[loonunit]

I believe that the avian (bird) chips would be small enough and work well.
The question is.....
Where would you put one?

My thoughts are under the skin, along side the spine, just forward of the the cloaca. Any opinions?

I have one microchipped animal, and his is located an inch forward of the cloaca (less than an inch when he was little, I guess), but down low, just above the line where the belly turns white.
